The ISO 50001 Energy Management System enables organizations to systematically improve their energy performance. One of the key aspects of this process is the determination of Energy Performance Indicators (EnPIs). EnPIs are quantitative indicators used to measure and monitor the energy performance of an organization.

The determination of EnPIs is closely linked to the energy baseline (EnB). To establish the baseline, the organization must first analyze its main energy-consuming activities and processes. Then, the variables affecting these activities (such as production volume, weather conditions, or working hours) must be identified.

Next, suitable indicators are selected based on the specific activity. These indicators can be simple (e.g., kWh per production unit) or based on multivariable models. The choice depends on the context and the processes involved. The main goal is to accurately and realistically reflect changes in energy performance.

Once EnPIs are determined, they should be monitored continuously, changes must be documented, and improvements in energy performance should be evaluated. Based on these indicators, the organization can establish energy objectives and targets, thus ensuring continual improvement.

Within the ISO 50001 framework, properly selected EnPIs make a significant contribution not only to improving energy efficiency but also to achieving financial savings.

Remember: with well-defined energy performance indicators, you're saving not just resources—but also your budget!
